many articles on her own as well as in cooperation with other scientists. In 1951, for example, she worked with J. Lamer to identify a new enzyme, amylo-1, 6-glucosidase--or more commonly, the debrancher. This helped her to define chemically the structure of glycogen, and it also helped with applications of her research. In 1955 she furthered her long- held interest in hereditary glycogen storage diseases in children. The first of its kind, her work showed how enzyme defects or deficiencies can lead to congenital metabolic diseases.
Gerty Cori died on October 26, 1957, after a decade-long battle with myelosclerosis, a bone-marrow disease. In her final years, she reduced her sporting and climbing activities but did not avoid the lab and her students, particularly foreign students with whom she felt a special kinship. Born an Austrian, Gerty Cori died an American. In her own words, "I believe that the benefits of two civilizations . . . have been essential to whatever contributions I have been able to make to science."7
